AUTOMATIC WATER CONTR/GL FOR FURNACE AR-MOSTENEBS.

Application tiled Getober 3,

T0 all whom it may concern.'

Be it known that 1, JOHN L. SKUTTLE, a

citizen of the United lStates, residing at Y evaporating pans of hot-air furnaces commonly known as air-moisteners, and whereby the water-inlet valve of the pan is automatically opened upon a lowering of the level of the liquid within the pan.

`A further object is the provision of a `cap of special form and adapted for pivotally mounting a float-member thereon while accommodating the valve operated by the float in its reciprocating movements aswell as allowing for a removal of the valve and its stem without adjusting the cap. Y

A still further object is to provide a pipe section provided with a valve seat and posi `tioned eXteriorly of an evaporating pan, the

Y said section coperating with a cap securedl thereto and positioned within the panand adapted to mount both a float and valve member operatively thereon.

With these general objects in Vview, and others that will appear as the nature ofthe invention is better understood, the same consists in the novel combination and arrangement of parts to be hereinafter more fully described, illustrated in the accompanying drawings, and set forth inthe appended claims. i Y

1n the drawings forming a part ofthis application and in which like-designating characters refer to corresponding parts throughout the several views,

Figure 1 is a central longitudinal vertical sectional view through the evaporating pan of a furnace and through the invention in- Y stalled thereon. Fig. 2 is an enlarged detail view partly broken away of the mounting bushing of the device and the members carried thereby. Fig. 3 is a perspective view of the valve and its stem detached, and Fig. 4 is a perspective view of the mounting cap.

Referring more in detail to the drawing,

1914. Serial No. 854,855.

it is to be understood that the present device is employed in connection with an evaporating pan 10 which constitutes an air moistener, being of the usual form provided in connection with hot-air furnaces for moistening the heated air which is generated by the furnace through the agency of fluid 11 such as water contained inthe pan. The water supply pipe 12 is coupled to the pipe section 13 which in turn has the usual elbow 111 thereon. Y

The pan 10 has a perforation 15 through the wall thereof and through which perforation a sleeve 1G is screwed, the said sleeve being externally screw-threaded throughout its entire length and having a pipe section 17 engaging its outer end which pipe section has a threaded engagement with the said elbow 14;. A cap 18 is threaded upon the sleeve interiorly of the pan while similar gaskets 19 encircle the sleeve 1G on the opposite sides of the pan wallV and are forcibly engaged by the section 17 and cap 18 for forming an air and water tight connection.

A ball Heat 2O is provided within the pan partially immersed within the water contained therein and has a rod 21 secured thereto which isprovided with a flattened head 22 having pivotal connection with a slotted post 23 upon the end wall 24 of the bushing, the said head4 being positioned through the slot 25 of the said post and mounted upon the removable bolt 26.

A valve stem 27 has a head 2S at one end provided with a longitudinal slot 29 which receives the rod head 22 and is connected thereto pivotally by means of another removable bolt 30. The end wall 24 of the cap has an eccentrically arranged opening `31 therein and through which the valve stem 27 extends, while a washer valve 32 of slightly less diameter than the diameter of the opening 31 is screwed u on the threaded free end 83 of the stem 27, eing adjustably retained by means of the set-nut 34.

The manner of assembling the device will be apparent from the present description in that, with the bolt 26 removed, for disengaging the rod head from the bushing post the float and valve are disconnected therefrom although such parts are connected together. The sleeve is positioned through the pan perforation and the section 17 and the cap 18 are firmly screwed against the packings 19 and upon the sleeve 16, it being noted that the capis provided with opposite I longitudinal ribs adaptable as wrench V hold surfaces.k

' the rod head then pivoted to the post 23 by inserting the bolt 26. .lt-will thus be seen that the cap and pipe section 17 become sub-.

vstantially iixed members of the pan, and

that for repairing the valve or the float members, a removal of the bolt 26 alone is Y requisite, it being noted also that the valveV 32 is readily adjustedupon the valve stem and secured by means-of the nut 34 as itbecomes worn by` constant contact with .the valve seat. v Y Y While thev forms of the invention herein shown are preferred, minor changes may be made therein without departing from the spirit and scope of the invention as claimed. A lowering of the level of the water within the pan results from evaporation and there-` upon, the float 2O lowers with the water, which eXertsapull upon the valve 32 unseating the saine from its seat 37 andallowing water to enter the pan until the normal y level thereof is restored. An inflow of water to the pan is thus automatically eected upon eva-poration, thus automaticallymaintain'ingja substantially'normal waterilevel What is claimed as new is LA device of the class described comprising in combination with a vpan having a perforation through the side thereof, a sleeve screw-threaded within said perforation, gaskets mounted upon said sleeve engaging the opposite faces of the pan side, a4 pipe section having a tapered inner portion and screw threaded upon the outerlend of said sleeve in contact with the outer one of said gaskets, a cap screw threaded upon the C'opies ofthis patent-may be obtained for with said float for cooperating with said tapered inner portion.

2. A device of the class described com? prisinga pan'having aperforation therethrough, an externally threaded sleeve threaded through said perforation, gaskets 'threaded upon said'sleeve and engaging the i opposite .faces of the wall of the pan, a pipe i section threaded upon the outer end of said sleeve in engagement with oneof said gaskets, and having a tapered bore portion, a cap screwthreaded upon the inner endrof said sleeve and havingan end ,wall `provided with an eccentrically `arranged `opening therethrough, oppositely positioned wrenchr4 hold surfaces upon said cap, a'post projecting from said vend wall lof .the cap and eccentrically .arranged thereon and provided with a longitudinal slot`,a floatwithin said pan, a rod secured to said float and having an enlarged flattened VheadY positioned within said post-slot, a removable bolt connecting said post and head pivotally together, a

valve stem pivoted tothe said'head and pro-A jecting through said capA opening and the;v said sleever andk into the said pipe sectionV and a valve for coperating withsaid'ta-t pered portion adj ustablyfniounted upon said stem of less diameter than the diameter of said opening anda lock n ut forY 'saidvalve mounted uponsaid stem.' i

3. A oat valve Vmounting cap.. of substantially tubular forni comprising an end wall'having an eccentrically positioned opening therethrough, diametrically. posif tioned., longitudinal wrench hold surfaces upon said cap, a post projecting Vfrom the said end wall and having a longitudinalslot in the free end thereof and eccentrically po-,f

sitioned von saidvend wall andprovidedwith a pivot mounting in the longitudinal slot.
